Normally I run about 20 miles a week (4-5/day) and recently I've been upping it to 6, sometimes 7 with varying levels of success. I used to be around 9:30/9:00 per mile but recently I've been solidly under 9:00 closer to 8:30/mile. So the next logical step would be to continue to up mileage and eventually do a half-marathon. I don't think this would be within the next month or two but before the end of the year or early next year. Before I google "how to prepare to run a half marathon" and find out which fitness blog has the best SEO, has anyone prepared for this before?
I’ve run 20+ halfs. They’re my favourite distance.
I guess what’s your goal? Just to finish or do you have a goal time in mind? How much time do you have to train? And when is the race/how many weeks out are you?
If your goal is just to get up to that distance, add 1mile to your long run and 2miles to your total distance for four weeks straight. On week 5, take a recovery week, and drop down ~25% then back to what you did in week 4 for week 6 and repeat until you get to 13.1
So, if you’re at 20miles total and a long run of 6miles right now, it could look like:
W1: LR - 6m / Total - 22
W2: LR - 7m / Total - 24
W3: LR - 8m / Total - 26
W4: LR - 9m / Total - 28
W5(Recovery): LR: 7 / Total 24
W6: LR - 9m / Total - 28
W7: LR - 10m / Total - 30
W8: LR - 11m / Total - 32
W9: LR - 12m / Total - 34
W10: LR - 13m / Total - 36
W11 (Taper): LR - 9m / Total - 28
W12 (Race Week): LR - 13.1 / Total 20
That’s just a rough plan, but 12 weeks should easily get you there. I’d suggest at least 3 runs a week, with one day of intervals (ex. 8 x 400m, with equal rest), one longer intervals (4 x 2k, with half rest) and your long run day. Other days can be easy runs at conversational pace or cross training (biking, team sport, etc). I’d also recommend a couple days of core and a day of strength, but whatever works for you, there’s only so much time in the day.
